VTSUAL WEATHER-SCREEN.

To all whom it may concern:

Be it known that we, Sui-Uni AUGUSTINE DE NORMANVILLE and LEsLIE HARCOURT KENT, both subjects of the Kin of Great Britain, residing at Ealing, Midd esex, England, and Stanmore, Midd esex, England, respectively, have invented certain new and useful Im rovements in Visual Weather- Screens, 0 which the following is a specification.

This invention relates to improvements in visual weather screens-forming art of our application filed May 8, 1917, erial No. 167,381, allowed Sept. 12, 1918, in which a transparent disk is rotated so that rain and spray driving against it are thrown off under centrifugal action.

The object of the present invention is to facilitate the application of a screen of the above type to existing windows, screens or look-out apertures, or as a face guard in the open, and preferably in such a manner that the device can be removed readily from its support for storage when not required, and also preferably so that when replaced for use it is connected automatically with the source of power by which it is driven.

One embodiment of the invention, in which electric power is used to drive the device, is illustrated. b the accompanying drawings in which Figure 1 is a sectional side elevation showing the device applied to a motor-car screen.

Fig. 2 is a plan partly in section of a bracket for supporting the device and provided with electric contacts, and

Fig. 3 is a front elvation on a reduced scale of the device detached.

- In this form a transparent disk 10, with its saindle 14, spindle bearing 13, pedestal 2 and a motor 16 are all arranged as a selfcontained unit.detachable for stowage urposes. Means are also provided by w ich the act of placing the unit in position completes automatically an electrical connection for the motor. In this form the disk 10 clamped between the nuts 15, 15, rotates with the spindle 14 which is carried in bearings 13, on the head of the pedestal 2. The electric motor 16 in the base of the pedestal drives a shaft 17 fitted with a bevel wheel 37 which engages with a bevel wheel 36 on the'spindle 14. The lower end of the motor shaft runs in a step bearing 48. The motor 16 with the pedestal 2, and disk 10, are sup- Speciflcation of Letters Patent.

Patented May 11, 1920.

Application filed December 10, 1918. serial 110. 266,178.

ported by a bracket 44 mounted in any convement manner in front of the lower rail 162 of the existing motor car or other screen 1. The bracket has a split ring 45 adapted to be tightened by a screw 46 so as to clamp firmly a cylindrical extension 47 on the motor 16. Contact plugs 48, screwed into insulating bushes 55 in the motor casing to allow for adjustment, are adapted to enter holes 51 in contact plates 50 mounted on an insulating block 52 screwed to the bracket 44. The leads from an electric cable 54 are connected by terminal screws 53 to the plates 50. The inner ends of the plugs 49 engage with the motor terminal screws 56 on an insulating block 57 mounted inside the motor casing.

When the screw 46 is slackened the unit can be removed, as indicated in Fig. 3, and the electric contact will be broken, whereas when the unit is replaced the plugs 49 enter the holes 51 in the plates 50 and contact is made automatically no skill being required on the part of the user.

A guard 58, preferably faced on its edge with rubber 62 to bear against the car screen 1, is provided for the purpose of preventing moisture passing down the screen 1 between it and the disk 10. The guard 58 is conveniently carried by wires 59 supported by a collar 60 clamped between a cap 61 and the head of the pedestal 2.

We.claim:-

1. A visual weather screen comprising a transparent disk having a spindle, a edestal for supportin said spindle, means or drivingsaid spind ecomprising an electric motor, said pedestal being carried b said motor, a flange on said motor; a brac et adapted to embrace said flange to support said motor, said bracket having contacts in connection with a source of electric current and being adapted to make contact with the terminals of the motor when said motor is laced on said bracket, substantiall as an for the purpose hereinbefore set orth.

2. A visual weather screen comprisin a transparent disk havin a spindle, a pc estal for supporting sai spindle, means for driving said spindle comprising an electric motor, said edestal being carried by said motor, a c lindrical flange on said motor,

a bracket or embracin said flange suport said motor, said racket bein in t orm of a split ring, means for c amping e perforated contact lates carried by sai mine on said motor in the form of in adapted to enter the erforations 0 said contact plates when t 0 motor is laced on said bracket, substantially as and or the purpose hereinbefore set forth.

3. In combination a stationalg transparent screen, a rotary transparent isk, havin a spindle, a edestal for supporting sai spindle with t e disk in close re ation to said screen, an electric motor connected to said pedestal for drivin the aforesaid spindle, a bracket on the a oresaid screen for sup- 1,sao,ost

In testimony whereof we have signed our 2 names to this specification in the presence of two subscribing witnesses.
